Watch out Apple iPad, the BlackBerry PlayBook Tablet is Coming!

First, expect to buy BlackBerry PlayBook in the United States by early 2011.

The BlackBerry PlayBook Tablet, with it’s BlackBerry Tablet OS, promises fast web browsing, true multitasking, high performance multimedia, advanced security features, out-of-the-box enterprise support and a new development platform for IT departments and developers.

The biggest question is screen size.

We have the iPhone and other smartphones (screen size: 3.5 inches), the Dell Streak with Google’s Android OS (5 inches) and the iPad (9.7 inches).

Samsung’s new Galaxy, also with a touch screen that measures 7 inches diagonally, will be released in late October or early November.
